b

Inspect the main journals

1

Using a micrometer, measure the diameter of each main journal

Standard journal diameter: 66.988 to 67.000 mm (2.6373 to 2.6378 in.)

If the diameter is not as specified, check the oil clearance If necessary, replace the
crankshaft

2

Check each main journal for taper and out-of-round as shown in the illustration

Maximum taper and out-of-round: 0.02 mm (0.000787 in.)

If the taper and out-of-round is greater than the maximum, replace the crankshaft

c

Inspect the crank pins

1

Using a micrometer, measure the diameter of each crank pin

Standard crank pin diameter: 55.982 to 56.000 mm (2.2040 to 2.2047 in.)

If the diameter is not as specified, check the oil clearance If necessary, replace the
crankshaft

INSPECT CRANKSHAFT OIL CLEARANCE

a

Clean each main journal and bearing

b

Check each main journal and bearing for pitting and scratches

If the journal or bearing is damaged, replace the bearing

c

Place the crankshaft on the cylinder block

d

Lay a strip of Plastigage across each journal

e

Install the crankshaft bearing caps (see REASSEMBLY )

f

Remove the 30 bolts and bearing caps

g

Measure the plastigage at its widest point

If the oil clearance is greater than the maximum, replace the bearings If necessary, replace the
crankshaft

HINT:

If replacing a bearing, replace it with one that has the same number If the number of the bearing
cannot be determined, select the correct bearing by adding together the numbers imprinted on the
cylinder block and crankshaft Refer to the table below for the appropriate bearing number There
are 6 sizes of standard bearings For the No 1 and No 5 position bearings, use bearings marked 4,
5, 6, 7, 8 and 9 For other bearings, use bearings marked 3, 4, 5, 6, 7 and 8
